I think the greatest possible contribution to all of science that hacker news (the piece of software + the community) could provide would be to extend its general self-reinforcing conversational tone to include issues of conscience and the ethical, moral, and political implications of the subjects discussed here.

That sounds great, but isn't doable. It only seems doable, because of the dynamic described here: https://news.ycombinator.com/item?id=16438476. What would actually happen is that it would make the community nastier and dumber until it died. Whom the gods would destroy, &c.
The fundamental tradeoff: the better HN gets, the more people want to use it for things that worsen it. This puts a cap on how good HN can ever get. All we can do is find ways to wriggle out of that tradeoff here and there.
